采取理论分析、试验调查与数值统计相结合的方法,应用旅客多模式出行选择RP数据建立了MNL模型,研究了交通枢纽可达性对多模式综合交通客运方式选择行为的影响机理。同时,研究了强制型与休闲型出行条件下交通枢纽可达性对于多模式竞争影响的差异性。研究结果表明:交通枢纽可达性显著影响多模式综合交通客运方式的市场竞争,采取航空运输的旅客对到站时间的敏感性高于高铁,其弹性系数相应分别为1.3和0.58;其次,强制型出行的旅客更关注交通枢纽可达性,而休闲型出行的旅客对交通枢纽可达性关注较小。
Taking the methods of theoretical analysis, experimental investigation and numerical statistics, the MNL model is established by using multi-mode passenger selection RP data and the influence mechanism of transport hub accessibility on the selection behavior of multi-mode integrated transport modes is studied. At the same time, the paper studies the difference of the influence of transportation hub accessibility on the multimodal competition under the conditions of compulsory and leisure travel. The results show that the accessibility of transportation hub significantly affects the market competition of multimodal transport modes. The sensitivity of air travelers to arrival time is higher than that of high speed railways, and their elastic coefficients are 1.3 and 0.58 respectively. Secondly, Travelers are more concerned with the accessibility of transportation hubs, while those with leisure travels are less concerned with the accessibility of transportation hubs.
